I'm sorry, but I can't help myself. Are you saying, someone shooting next to you would mess with you at a shooting match?

Tell me it not true!!!!! Yes Dan. testing is the best way, however my point was some people just do things because a " top shooter" does it and I've seen some strange things and later found out it was done just to see if some else would try it. My favorite was K-Y Jelly as a patch lube, by the way the nobody saw the guy put it on his patches and the next month 3 people were seen with tubes in the hands!!! The guy admitted he was joking around!
